The MOSDEF survey: a stellar mass-SFR-metallicity relation exists at $z\sim2.3$

, 2018
We investigate the nature of the relation among stellar mass, star-formation rate, and gas-phase metallicity (the M$_*$-SFR-Z relation) at high redshifts using a sample of 260 star-forming galaxies at $z\sim2.3$ from the MOSDEF survey.

The Atomic Gas Properties of Green Pea Galaxies: Connections to Lyman Continuum Leakage

The Astrophysical Journal Letters
We have used the Green Bank Telescope to search for H i 21 cm emission from 30 Green Pea galaxies (GPs) at z  ≈ 0.012–0.045, obtaining 7 detections of H i 21 cm emission and 17 upper limits on the H i mass.

The MOSDEF Survey: Electron Density and Ionization Parameter at $z\sim2.3$

, 2015
Using observations from the MOSFIRE Deep Evolution Field (MOSDEF) survey, we investigate the physical conditions of star-forming regions in $z\sim2.3$ galaxies, specifically the electron density and ionization state.

Neutral Gas Properties and Ly$\alpha$ Escape in Extreme Green Pea Galaxies [PDF]

, 2019
Mechanisms regulating the escape of Ly$\alpha$ photons and ionizing radiation remain poorly understood. To study these processes we analyze VLA 21cm observations of one Green Pea (GP), J160810+352809 (hereafter J1608), and HST COS spectra of 17 GP ...

Atomically Revealing Bulk Point Defect Dynamics in Hydrogen‐Driven γ‐Fe2O3 → Fe3O4 → FeO Transformation

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
In situ TEM uncovers the atomic‐scale mechanisms underlying hydrogen‐driven γ‐Fe2O3→Fe3O4→FeO reduction. In γ‐Fe2O3, oxygen vacancies cluster around intrinsic Fe vacancies, leading to nanopore formation, whereas in Fe3O4, vacancy aggregation is suppressed, preserving a dense structure.

Does the Balassa-Samuelson Hypothesis Hold for Asian Countries? An Empirical Analysis using Panel Data Cointegration Tests [PDF]

, 2002
This paper tests empirically the Balassa-Samuelson (BS) hypothesis using annual data for 6 Asian countries. We apply new panel data cointegration techniques recently developed by Pedroni (2000) and we compare the results with those obtained with ...
